Light wells for light and ventilation were common before modern HVAC and lighting. No one wanted an office/desk far from a window. Now due to the former and also desire for larger floor plates these often get filled in. Another example is the old NY Life bldng(catholic diocese).

I knew light wells were a thing--I did not realize they were often filled in. That strikes me as a somewhat large undertaking. Very interesting.

This also explains why there are "windows" in some of the conference rooms in the Trust building.
